Open a folding screen for face-to-face study: CardFacing keeps your question and answer controls clear of the fold.
Make decks of your own words, definitions and questions. Show a question, listen, reveal the answer and mark it right or wrong. Cards you miss more often appear earlier in the next round. Your session and grading stay saved between visits.
Import cards from a UTF-8 CSV file with front and back columns. Two decks are free; a one-time purchase removes the deck limit. No ads or account required.
On a non-folding iPhone, reveal and grade cards on one screen and pass the phone to your study partner.
